It was the perfect gift for the Yorkie my wife who wallows on the sofas and bed He growls when I wish to dislodge supported in this by his mistress, who demand that I left alone. A self-heating doggie bed. No but allo. The mutt especially wanted to go once I threw a biscuit in it. He even slept several times. Unfortunately he'd rather come climb on our bed, especially in our sleep. I can not stand it. In any event during the day, he slips it willingly especially when I watch TV. Mas when my wife arrives he begins to climb the sofa. There should be a system or tether straps to secure the animal (one star less).
